DEVELOPING AN ALT TEXT BUTTON FOR IMAGES ON MY WEBSITE

This dev created an HTML and CSS-only "Alt" button for images on their website inspired by Mastodon's similar feature that allows users to view alt text descriptions by clicking a button. The solution uses a checkbox trick with CSS styling to show/hide alt text content when the button is clicked, positioning the actual checkbox off-screen while keeping the label visible as the clickable button.

WHAT IS DEVELOPER MARKETING?

Developer marketing is about understanding and communicating with developers in a human way.
